What do scientists say about coral bleaching?
Summary: A scientist has made a major breakthrough in the understanding of coral bleaching — a process that causes corals to lose their color and eventually leads to their death. The process is triggered by warmer ocean temperatures, and, according to the study, it begins much earlier than previously thought.
What do scientists think causes coral bleaching?
The leading cause of coral bleaching is climate change. A warming planet means a warming ocean, and a change in water temperature—as little as 2 degrees Fahrenheit—can cause coral to drive out algae. Coral may bleach for other reasons, like extremely low tides, pollution, or too much sunlight.
What are scientists doing to help coral reefs?
EPA protects coral reefs by implementing Clean Water Act programs that protect water quality in watersheds and coastal zones of coral reef areas. EPA also supports efforts to monitor and assess the condition of U.S. coral reefs, and conducts research into the causes of coral reef deterioration.
Is coral bleaching a big issue?
Yes. Severe, widespread coral bleaching is an issue on coral reefs around the world as a result of changes to the Earth's climate.
What is Australia doing to stop coral bleaching?
The Reef Trust is the Australian Government's flagship investment program to support the delivery of the Reef 2050 Long-Term Sustainability Plan (Reef 2050 Plan). The Australian Government has committed over $1.3 billion to the Reef Trust to address key threats to the reef.

What are the major threats to coral reefs?
Threats to Coral Reefs
- Physical damage or destruction from coastal development, dredging, quarrying, destructive fishing practices and gear, boat anchors and groundings, and recreational misuse (touching or removing corals).
- Pollution that originates on land but finds its way into coastal waters.
How are scientists preventing coral bleaching?
One option is to create more marine protected areas—essentially national parks in the ocean. Scientists say creating marine refuges, where fishing, mining, and recreating are off limits, make the reefs healthier, and so more resilient.
What is one way scientists trying to save the coral reefs?
Scientists are looking at breeding these resilient corals, which could be used to restore reefs. Other protections, such as preventing pollution and overfishing, are also key, Kleypas says. Still, all these efforts to help corals adapt to hotter temperatures won't be enough if greenhouse gas emissions remain high.
